are you sure the resolution is supported by the scanner?

I am not sure it supports 499 x 499 but I scanned an image with resolution 200 x 200 using the scanner alone and it works. When I try to scan the image using JTwain with 200x 200 dpi settings I get a 96 x 96 dpi image.

do a dat_capability msg_get for the resolution before you scan and make sure you really set the resolution or at lest check the answer from the source when you set the resolution to make sure your command was correctly executed.

Could you please post an example of code of how to use dat_capability and msg_get from Java?

How do I check the answer from the source?

Thanks.
